If you don't need the money, take time off. When I left the last startup I co-founded, I decided to set an arbitrary "1 whole year" date, during which time I would explore my own projects, hear about other peoples new ideas, and talk to existing larger startups (Dropbox, etc). But I wouldn't allow myself to commit to anything until about a year was over. It's too easy to be come enamored w/ half-baked ideas, and I wanted to make sure the next one was meaningful and had a high probability of success. Long story short, I learned a ton during that year, turned down some great options, and eventually chose the BEST of all possible options. (Starting a meaningful company w/ killer co-founders, gaining traction, and having a blast)

If you have the chance, give yourself the space! It'll be worth it.
